-----------------------------------------
I raised SOLR-6370 to catch such issues proactively.
> DistributedQueue (and it's use in OCP) leaks ZK Watches
> -------------------------------------------------------
>
> Key: SOLR-6336
> URL: https://issues.apache.org/jira/browse/SOLR-6336
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Reporter: Ramkumar Aiyengar
> Assignee: Mark Miller
> Fix For: 5.0, 4.10
>
>
> The current {{DistributedQueue}} implementation leaks ZK watches whenever it
> finds children or times out on finding one. OCP uses this in its event loop
> and can loop tight in some conditions (when exclusivity checks fail), leading
> to lots of watches which get triggered together on the next event (could be a
> while for some activities like shard splitting).
> This gets exposed by SOLR-6261 which spawns a new thread for every parallel
> watch event.
